Official summary
TSB: Battery Electric Vehicles (BEVs) store electricity received via an external power source in the BEV traction battery. When the BEV is not used for a period of 30 days or more, the traction battery self-discharges, thus reducing vehicle travel range. To prevent the BEV traction battery from fully discharging it is necessary to maintain the charge level of the BEV traction battery.

What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
